Is it possible to change location based on proximity to another object?
Adjacency



Consider a driver in the Delta Location X which associates with the X dimension of the adjacent object.  Suit Location index to needs.



Image above.  Cube has smaller X dimension.



The cone is a parent as depicted in the Outliner Window.  The sphere delta location is determined by x dimension of the beveled cube.  The alignment must be taken into consideration.  Here the cube origin is the geometric center, thus the script has the corresponding math.

The blue object represents text.
